Hi!
If my memory does not let me down, a DNS server makes the translation between
IP adresses and hostnames. On any OS, you can specify several DNS servers, so
if the first fails down, it tries to reach the second one.
But what I have to handle is this: someone on the network requests
www.mywebsite.com. The external FW catchs the request, performs a NAT and
redirects it to the webserver. But the FW has to know to which web server it
has to redirect the request...
PS: My web servers are web servers only, not at all DNS servers ...

Hmmm... could you not simply add the second web server to the end of the list
for DNS entries? Failing contact with the first listed server it should contact
the next entry in line.
Correct me if I'm wrong, folks. :)

Subject: Securing web site with redundancy ?
Hi all !
I was wondering if there was a way to set up 2 "redundant" web servers
(identical web sites), i.e. when one crashes, the other one takes the
connection over. The same thing which is already available for firewalls (high
disponibility), but with web servers.
We would have 2 Windozes in a DMZ with IIS as the web server, and a pix
firewall between the dmz and Internet. Is there any tool allowing this out
there ? I tried to google quite a while, but without any chance...
Some one has an idea ?
Cheers list !
